Title: Method of determining surface relief without making contact with the surface
Inventor: CAUSSIGNAC JEAN-MARIE
IPC: G01B11/24
Filed: 1987-01-28
Granted: 1990-11-06
Abstract: ABSTRACT OF THE DISCLOSURE            A method of rapidly determining surface relief of an object or a structure without making contact therewith based on quantifying the degree to which the image of an illuminated point or small spot on the surface is defocussed.  Said point or spot is illuminated by a source of electromagnetic radiation such as a laser, and the relief is determined in the form of a profile where the height of any point on the profile is represented by the ratio of the energy values of two beams derived by splitting a single beam reflected from the surface under investigation: one of the    beams acting as a reference and the other of      beams being limited by the action of a diaphragm and constituting a measurement beam.

Title: Two part mastitis cannula cap

Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE A  system  having  a  microprocessor  to  provide  an adjustable  control  of  the  temperature  and  pressure  of  water at  the  outlet  of  a  single  adjustable  valve.   The  water temperature  at  the  valve  outlet  is  constantly monitored.   A processor compares the actual water temperature with a specif-ically requested temperature for the water at the valve outlet, and  provides  signals  to  relays  and  a  control  circuit  for  a motor which adjusts the temperature of water by the relative proportions of hot and cold water discharged through the valving to  the  outlet.   The  system with  the  microprocessor  provides a multi-speed  control  of  the motor  having  variations  in  the speed of adjustment of the valve so as to effect a quick valve movement  to  a  temperature  in  the  vicinity  of  the  desired temperature  after  which  fine  tuning  provides  the  exactly requested temperature.  The calculations of the microprocessor by including continuous monitoring of the valve positions and the  water  temperature  coordinates  the  relative  positioning of the valve in the mixing of the hot and cold water with the regulations of  the water temperature by mixture in the valve so that the  instructions  from the microprocessor in response to  the water temperature are accommodated  to  fully open and fully closed positions of the valve.

Abstract: METHOD AND APPARATUS FOR SORTING WOOD CHIPS                  ABSTRACT OF THE DISCLOSURE     A wood chip sorter comprises a shell (22) which at least partially defines a substantially cylindrical sorting chamber (26) into which wood chips are introduced.   The shell (22) has a plurality of rotatable shafts (28) mounted thereon with the axes (72) of the shafts (28) being circularly arranged about a central axis (24) of the shell (22).  Each shaft  (28) has a plurality of discs (80) mounted at spaced intervals thereon with discs of adjacent shafts (28) intermeshing radially to form essentially axial spaces (84) therebetween.  A drive and transmission system (30) revolve the shell (22) about the central axis (24) of the shell(22).  A planetary gear system (32) facilitates rotation of the shafts (28) about their axes (72) as the shell (22) revolves.  The discs (80) are shaped to have greatest axial width at central portions thereof, and taper to a lesser axial width at their circumference.  The discs (80) are formed from an abrasion-resistant material.  Compressible spacer members (82) are mounted between adjacent discs on a shaft.  An inlet (34) is configured to include a helically threaded feed member (46) which extends into the shell (22) and along the central axis (24) thereof.   The inlet (120) facilitates input of the wood chips so that chips in a desired thickness range have the opportunity to pass through the axial spaces (84) existing between intermeshing,  (80) discs of adjacent shafts (28).

Abstract: FITTED SHEET HEMMER                      Abstract Sheet  material  (30)  is  cut  into  rectangular segments (35).   The segments are then moved parallel to  their  cut  edges  rapidly  away  from  the  cutting station  into a  slower operating  first sewing  station (40) where elastic bands are sewn to the cut head and foot edge portions of the segment.  The rapidly moving trailing portion of the segment (35) of sheet material is temporarily accumulated at the accumulation station (39) and  progressively fed  at a lower rate from the accumulation station to the first sewing station.  The head and foot edge portions are folded into overlying relationship  with  respect  the  main  body portion  by passing the main body portion through a U-shaped turn and at the same time passing the head and foot edge portions through a pair of 90 degree turns.   Sewing machines are moved first inwardly and then outwardly across the folded edge portions of the segment, thus forming  the  sewn  line  of  chain  stitching  at  the corners of the bedsheet.
